[Elecraft] Babies at play as seen on the P3

[Drew AF2Z]

There are ionospheric chirp sweepers that go through the hf spectrum 
every couple of minutes. They sound like someone lightly clearing his 
throat. Have no idea what it looks like on the pan display. On a given 
frequency you'll hear the chirp at the exact same time every couple of 
minutes
